uvsplit Item Complexity Research Milestone Time split up frequency band moderate none 8 5d
Add a parameter to uvplit to split up wide bands into a number of sub-bands. This could either be a nsub type keyword specifying the number of bands to split into, or a maxbandwidth keyword to limit the maximum bandwidth of the output files. Some thought needs to go into the naming scheme of the output files, since sub-bands and zoom bands could have identical center frequencies.
The current naming scheme is to use the source name and center frequency (rounded to the nearest integer). For example, hh137.4800 (HH object 137 and 4800 MHz center frequency). The following defines CABB modes:

There is perhaps a functional overlap with the bbcal, which at the moment is proposed to split an 8GHz observation into 2GHz sub-bands.
It is also interesting that the Pulsar data from the digital filterbanks (CABB-style boards) can be split using the ATNF Pulsar software (TEMPO2?) It may be possible to re-use that code here. MarkCalabretta? has also modified LIVEDATA to cope with MOPS data which includes both broad and zoombands.
